WebThe training set is used to build a classiﬁcation model, which is subsequently applied to the test set, which consists of records with unknown class labels. Evaluation of the performance of a classiﬁcation model is based on the counts of test records correctly and incorrectly predicted by the model. did heather dubrow get divorced
